A solid flex joint can ride harsh and gives little vibration damping. This upgrade swaps the Johnny Joint and its nylon spacers in a Currie 2-1/2in housing for steel spacers, a C-clip and a Duroflex rubber bushing. The Kevlar-infused rubber allows more misalignment than a solid joint.
The warranty is valid only when Duroflex joints are installed on both ends of the control arm.
